That would be helpful, but not strictly required.
One other case. If I'm developing a system of n processes that are
interdependent. If one dies, often times I find that I've not
programmed the others correctly, so they will dump core. If they are
all started out of the same dir, then you lose core dumps. It is best
to know which ones are dumping core so that you can fix them all at
once, rather than repeat n times for the n that are dumping core.
